XVILLIAM D. STANSBURY, OF JENKINTOIVN, PENNSYLVANIA.

SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 657,139, datedSeptember 4, 1900. Application filed December 29, 1899- Serial No.741,910. (No model.)

To ctZZ whom it may concern.-

Be it known that I, WILLIAM D. STANS- BURY, a citizen of the UnitedStates, residing at Jenkintown, in the county of Montgomery, State ofPennsylvania, have invented a new and useful ImprovementinShutter-Fasteners, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of a shutter-fastener of the order of aturnbuckle, the same being constructed as hereinafter described and itsnovel features pointed out in the claims.

Figure 1 represents a top or plan View of a shutter-fastener embodyingmy invention. Fig. 2 represents a front elevation thereof. Fig. 3represents a vertical section thereof. Fig. 4 represents a bottom planview of the adjacent portion of the shutter.

Similar letters of reference indicate corresponding parts in thedrawings.

Referring to the drawings, A designates a shank which is adapted to besecured to the proper portion of the wall of a building adjacent to theplace of location of a shutter when in open position. B designates earswhich project forward from said shank and have mounted thereon thegravitating latch C, which is formed of the head D and weighted arm E,pendent therefrom, said head being eccentrically mounted on said earsand hav ing somewhat converging sides forming the upwardly-projectingangular nose F, at the base of the inner face H of which is the shoulderG, said face being segmental for convenience of operation of the nosewhen it rides on the contiguous part of the shutter with which itengages in closing.

Interposed' between the ears B and shank A is the shoulder J, whichrises therefrom and serves to limit the opening motion of the shutter.

On the under side of the shutter is secured the slotted plate K, abovewhich is the opening or mortise L in the shutter in communica tion withthe slot of said plate, said slot and opening being adapted to receivethe nose F when the shutter is open.

The operation is as follows: When the shutter in opening reaches theright-lined face M of the nose F, it depresses the latter until saidface clears the contacting portion of the plate K. The nose is then nolonger controlled, and so rises and enters the plate K and recess L,where it remains owing to the action of the weighted arm E, and thus theshutter is held open. Should, however, the shutter be subjected to wind,whereby its tendency is to close, the outward pressure of the plate K onthe face H would cause the nose to move upwardly and forwardly and thusrelease the shutter; but here the shoulder G plays an important part inthat it abuts upwardly against said plate K and controls the noseagainst rising, so that said nose remains in the shutter and preservesits fastening action. When the nose is properly lowered, it emerges fromthe recess L and leaves the plate K and so clears the shutter, wherebythe latter is uncontrolled and may be readily removed from the fastenerand closed.

The opening or mortise L may be rectangular in form or somewhat V shape,as shown in dotted line in Fig. 3.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-

1. In a shutter-fastener, agravit-ating head, an ear on which said headis eccentrically mounted, a securing-shank carrying said ear, a weightedarm pendent from said head, an angular nose projecting upwardly fromsaid head, the rear upper face of said nose being segmental, and ahorizontal shoulder at the base of said rear upper face.

2. In a shutter-fastener, a gravitating head, an upwardly-projectingnose thereon, a horizontal shoulder at the base of the rear upper faceof said nose, a shank on which said head is mounted and a shoulder onsaid shank rearward of said shank on the head.

3. A shutter-fasten er consisting of a gravitating head, anupwardlyprojecting nose thereon, a weighted arm pendent from said head,an car on which said head is eccentrically mounted, a securing-shankcarrying said car, a shoulder rising from said shank and a shoulder onsaid'nose at the base of the rear upper face thereof.
